Mercedes E350e hybrid 2017

hey guys I’m new to this thread. So want to start by telling everyone a welcome hello. I have a brand new Mercedes hybrid E350e 213 bought in October last year and just tonight I got this message in my dash “ Auxiliary battery malfunction “ did some research and it was it was a small 12v battery in the trunk. Was wondering how much does one cost, and do I have to replace immediately etc... problems if I don’t replace immediately etc. Any info is welcomed.

Had this in my 2015. Bring it back to the dealer and they will replace it under warranty.
